Up for sale is a brand new, factory-sealed WSE (Westinghouse Security Electronics / NexWatch / Honeywell) DR4201 DigiReader Digital Proximity Reader internal circuit board replacement module. This enterprise-grade access control board is an authentic factory service replacement part designed to drop directly into Honeywell NexWatch DigiReader series wall-mount proximity proximity enclosures.

Because it is completely sealed inside its original factory protective pouch, the internal electronic components are preserved in pristine, untouched condition—totally protected from moisture, oxidation, and electrostatic damage.

VISUAL & OPERATIONAL REFERENCE GUIDE:

The physical status and exact identification numbers of this specific hardware unit are detailed directly across the source reference photos:

• Front Sealed Pouch View: As seen in the pictures, the main green printed circuit board assembly is shown completely secured within its factory-sealed, translucent pink anti-static (ESD) protective bag. A pre-wired gray communication tail pigtail harness is bundled neatly behind the board.

• Rear Sealed Pouch View: As seen in the pictures, the opposite side of the packaging reveals a separate heat-sealed pocket holding a genuine factory accessory/installation hardware package. A bright yellow "ATTENTION: OBSERVE PRECAUTIONS FOR HANDLING ELECTROSTATIC SENSITIVE DEVICES" factory warning label is affixed securely across the front.

• Hardware Sub-Pack Detail: Looking closely at the lower rear quadrant, as seen in the pictures, the sealed installation accessory pack contains a factory-fresh black L-shaped hex key wrench and its matching mounting set screw.

• Manufacturer & Model Validation: As seen in the pictures, looking directly through the protective plastic layer reveals crisp silkscreened markings on the green board confirming the manufacturer origin as "WSE", "PCB NO: 6200048", and the specific "MODEL DR4201". A clean white factory sticker displays the serial batch prefix (227110034) right alongside a "MADE IN China" country-of-origin label.

• Firmware & Configuration Detail: As seen in the pictures, a dedicated close-up highlights the primary microchip socket holding a clean factory firmware label marked "VERSION: 2.11 / P/N: 5400041". Adjacent to the chip, an integrated 5-position configuration DIP switch block (SW1) is entirely clean and untouched.

• Component & Wiring Protection: As seen in the pictures, the lower section of the mainboard highlights the factory-potted weatherproofing compound shielding the multi-color pigtail wiring connection nodes and the on-board signaling piezo buzzer module, ensuring long-term structural integrity.

TECHNICAL HIGHLIGHTS:

• Broad Credential Support: Fully compatible with standard NexWatch digital proximity credentials as well as standard HID proximity formats (including ProxCard II, ISOProx, and DuoProx).

• Dual Interface Versatility: Supports industry-standard low-cost RS-485 (WSE proprietary S-Net) data wiring or standard 26-bit / 34-bit Wiegand protocol outputs back to the host access control unit (ACU).

• Flexible Power Input: Engineered to operate efficiently across standard commercial low-voltage access panel loops (nominal 12VDC to 24VDC environments).

• Robust Security Features: Equipped with internal connections for hardware enclosure tamper monitoring and tri-color LED status/beeper diagnostics.

WHAT IS INCLUDED:

• 1x New Sealed WSE DR4201 Proximity Reader Circuit Board Assembly (As seen in the pictures)

• 1x Integrated Multi-Wire Pigtail Communication Harness (As seen in the pictures)

• 1x Sealed Installation Accessory Pack with L-Key & Set Screw (As seen in the pictures)
